People saying cars are hard to sell

[ebv8]

i have sold all my cars for a profit (on purchase price)
eg:
EB bought $5500 sold for $10500
AU1 XR8 ex cop car bought for $5300 from a dealer sold 1 year later for $6500
AU3 XR8 bought for $6000 sold for $7500 8 months later
AU2 wagon bought for $2000 sold for $2800 6 months later
VR wagon bought for $2000 sold for $2500 to same buyer bought back for $2000 sold for $2800
there is more as i have owned about 40 cars but now i know i'm going to lose money on my fiesta

point is i buy all my cars cheap and needing repairs or cleaning up as i love working on them and i think i have an idea on places to buy parts and get good deals
then when there is nothing else to fix that will gain a profit i sell it or i will modify but remove the mods before selling and sell parts separately.
